The idle air control valve manages the amount of air which flows into your engine. This, in turn, allows the valve to manage the idle speed of the engine.

Of course, the engine control unit communicates with the idle air control valve. It is what tells the valve when to open or close, resulting in more or less air flowing to the engine. The engine idle speed refers to the number of RPM revolutions per minute while the vehicle is not moving.

Based on the current conditions, the RPM adjusts accordingly by letting in just the right amount of air into the engine. However, when your idle air control valve is filthy or dirty, the idling process is more difficult. That is why you need to clean your idle air control valve periodically.
